DESCRIPTION:A transitive permutation group is called semiprimi
tive if every normal subgroup is either transitive
or semiregular. This class of groups includes all
primitive\, quasiprimitive and innately transitiv
e groups.\n\nThey have received recent attention d
ue to a conjecture of Poto&ccaron\;nik\, Spiga and
Verret that generalises the Weiss conjecture for
locally primitive graphs. In this talk I will disc
uss recent work with Luke Morgan that develops a g
eneral theory for the structure of semiprimitive g
roups and give some applications of the new theory
.
